Some new numbers:
PSV sales this week in Japan 61,152 (UP from last week's 60,561)
Wii U sales this week in Japan 9,089 (DOWN from last week's 9,528)
Sales totals in Japan:
PSV = 1,291,892
Wii U = 820,545
Wii U doing good catching up considering how much time it has been out compared to PSV, but the last 2 weeks Vita has increased the gap by over 100K in Japan.
